It handles multiple input formats\u2014iterators, numpy arrays, pandas DataFrames, dictionaries, and date-string pairs\u2014and supports different day-count conventions (ACT/360, 30E/360, etc.) used in fixed-income and corporate finance. The library also includes private equity metrics like PME+ and direct alpha, plus numpy-like vectorization for batch calculations.\n\nThe package solves the multiple IRR problem by searching for a positive result near 0.1 (matching Excel's default) and falling back to conservative lower IRR estimates when multiple solutions exist. It has no external runtime dependencies, includes type annotations, and is optimized for speed through its Rust backend. Typical use cases span investment analysis, portfolio performance measurement, and financial modeling where fast, accurate cash-flow calculations are needed.","worth_installing":"Yes. PyXIRR is a solid choice for financial calculations: it has no runtime dependencies, supports modern Python versions (3.7\u20133.14), carries a permissive license, and offers significant speed advantages through Rust. The medium install friction is mitigated by pre-built wheels for common platforms. The aging maintenance status (284 days since last release) is a minor concern but not a blocker, given the stable, focused scope of the library and zero known vulnerabilities."},"id":"pyxirr","links":{"html":"https://skillfed.io/packages/pyxirr","md":"https://skillfed.io/packages/pyxirr.md","pypi":"https://pypi.org/project/pyxirr/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-11-03","license_spdx":null,"license_treatment":"permissive","name":"pyxirr","python_support":"supports_current","summary":"Rust-powered collection of financial functions for Python."},"popularity":{"monthly_downloads":1082630,"position":4393,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.10.8"}
